Definitions

  • This invention relates to a loom heald used for forming a warp opening for weft insertion of a loom, a heald mounting frame member, and a loom using them.
  • a woven fabric is manufactured by a loom
  • a large number of loom healds are mounted on a plurality of heald mounting frames to form warp openings, and warps are passed through warp insertion holes provided in the loom heald.
  • at least a pair of heald mounting frames are operated so as to move up and down in directions opposite to each other to perform warp opening forming operations and sequentially send out the warps while wefting.
  • a conventional loom for a loom was formed by punching a metal plate to form predetermined mounting holes at both ends and a warp insertion hole at the center.
  • Metal loom healds have a constant thickness, little variation, and high durability, but because they are made of metal, they require a large force for molding and have a large mass, so there is a lot of driving energy during weaving. I needed it. Further, when the warp passes through the warp insertion hole of the loom heald, it rubs against the inner edge of the warp insertion hole, so that the warp is rubbed and the glue of the warped yarn is likely to fall off. It was. Of these metal loom healds, those with a short size of 30 cm or less were usually those with a thickness of 0.25 to 0.30 mm.
